I am submitting a grant request. The package will include four copies of the grant request, an executive summary, and a cover letter. The cover letter is very short and says in part "I have included four copies of the grant request for convenience of dissemination."
A friend suggested I add the encl. abbreviation at the bottom of my cover letter, but my logic tells me it's redundant and superfluous and may be of incorrect form in this situation since I state in the cover letter that the package contains enclosed documents. If the cover letter did not contain any reference to enclosed materials, I would have no dilemma and would add the encl. at the bottom.
I would like to hear opinion about whether to add encl. at the bottom of my cover letter.
